Description

Technical field:

[0001] The invention relates to the field of rail transportation, in particular to a locking frame dust cover. Background technology:

[0002] Turnouts are a key link in achieving track changes in rail transportation. In the turnout section of rail transportation, the locking rod can generally be driven by a switch machine, and then the locking rod drives the locking hook connected to the track to be changed to achieve the track movement of the track to be changed. The part where the locking rod and the locking hook are linked can pass through the locking frame installed on the fixed track. In this way, after the movement of the track to be changed is completed, the locking rod and the locking hook can be fixed by the locking frame, thereby locking the track of the turnout section. Under normal circumstances, the locking rod and the locking hook can move normally in the locking frame. However, since most tracks are outdoors and are often affected by harsh environments such as wind, sand, rain, and snow, it will cause the locking rod and the locking hook in the locking frame to accumulate sand, gravel, mud and other debris, hindering the movement of the locking rod and the locking hook. In order to ensure the reliability of the turnout equipment, a dust cover needs to be added to the locking frame to block the influence of the harsh environment.

[0003] At present, taking railway transportation in rail transportation as an example, dust covers are always added on top of the locking frame. In actual use, due to unexpected situations such as strong winds, debris may enter the locking rod and lock hook inside the locking frame from under the dust cover. Therefore, maintenance personnel need to frequently clean the locking frame, locking rod and lock hook, which consumes a lot of labor costs. Summary of the invention:

[0072] In order to clearly describe the technical solutions of the embodiments of the present invention, in the embodiments of the present invention, words such as "first" and "second" are used to distinguish between identical or similar items with basically the same functions and effects. Those skilled in the art can understand that words such as "first" and "second" do not limit the quantity and execution order.

[0073] Example 1:

[0074] The embodiment of the present invention provides a locking frame dust cover, which can be used in the field of rail transportation. Figure 1 、 2 As shown in , 3, and 4, it can be used for dustproofing the locking frame (2) on the track (1), and may include: a dustproof shell (6) and a dustproof cover (7); the dustproof shell (6) is placed on the bottom side of the track (1); the dustproof cover (7) is connected to the dustproof shell (6) through a first preset connection method; when the dustproof shell (6) and the dustproof cover (7) are connected, they hold the bottom side of the locking frame (2).

[0075] For better explanation, the application environment may also include a locking rod (3) and a locking hook (4).

[0076] When the dustproof shell (6) and the dustproof cover (7) are connected, the bottom side of the locking frame (2) is enclosed. At the same time, the locking frame dust cover formed by the connection of the two has an opening for the locking rod (3) and the lock hook (4) to move. The shape of the opening is not limited here.

[0077] The first preset connection method can be any one or a combination of hinge connection, lock connection, mortise and tenon connection, hinge connection, groove connection, screw connection, etc., or other similar connection methods or a combination of several connection methods, or magnetic connection, welding, etc. The specific connection method is not limited here, as long as it can achieve the connection between the dust cover (7) and the dust shell (6).

When the connection structure remains unchanged, all of these are implementations corresponding to the embodiments of the present invention.

[0082] Embodiments of the present invention provide a locking frame dust cover that can enclose the bottom of the locking frame through a dust cover positioned on the underside of the rail and a dust cap connected to the dust cover. Because the locking frame dust cover encloses the bottom of the locking frame, it not only provides dust protection similar to conventional designs but also prevents debris from entering the locking frame from underneath the dust cover. This eliminates the need for maintenance personnel to frequently clean the locking frame, locking rod, and lock hook, thereby saving labor costs.

The trigger (13-2) can be triggered manually, automatically through the movement of the locking rod (3) or the lock hook (4) or other movable parts, or automatically controlled by computer software program instructions, hardware program instructions or communication signals.

[0147] The oiler (13) is used for lubricating and maintaining the parts near the locking frame, and can realize lubricating and maintaining the parts near the locking frame without opening the dust cover of the locking frame, thereby reducing the labor cost of manual maintenance; and when the trigger (13-2) can be automatically triggered by the movement of the locking rod (3) or the lock hook (4) or other movable parts, the number of times of manual oiling and lubricating maintenance of the parts near the locking frame is further reduced, further reducing the labor cost of manual maintenance.

[0148] Furthermore, optionally, the oil injector (13) may further include an oil inlet (13-3); the oil inlet (13-3) is located at a lower level than the oil outlet (13-1).

[0149] The oil inlet (13-3) is used to receive the lubricating oil accumulated in the dust cover of the locking frame. The accumulated lubricating oil can be manually added lubricating oil or lubricating oil recovered from parts near the locking frame.

[0150] The oil inlet (13-3) can further reduce one or more of the labor cost and lubricating oil material cost for lubrication and maintenance of components near the locking frame.

[0151] It should be noted here that the structure and shape of the components shown in the figure in this embodiment are only illustrative examples for the convenience of explaining the present invention, and are not limitations on the present invention. Except for the specific implementation method shown in the figure, when the connection structure remains unchanged, all are implementation methods corresponding to the embodiments of the present invention.

[0152] Embodiments of the present invention provide a locking frame dust cover that can enclose the bottom of the locking frame via a dust cover positioned on the underside of the rail and a dust cap connected to the dust cover. Because the locking frame dust cover encloses the bottom of the locking frame, in addition to the dust protection provided by conventional technologies, it also prevents debris from entering the locking frame from underneath the dust cover. This eliminates the need for maintenance personnel to frequently clean the locking frame, locking rod, and lock hook, thereby saving labor costs. Furthermore, this feature allows lubrication and maintenance of components near the locking frame to be achieved through one or more structures, such as an oil suction device and a lubricator, reducing maintenance costs.
